I tend to agree that poly people tend to be more open-minded than the average non-poly population, but YMMV - I know that here in Upstate New York things are pretty conservative in general, so I don't know how comfortable people would be in general.
Personally, I would like to think of us being able to welcome everyone of any gender, or gender preference.
